Introduction: The use of a secondary titanium insert has a beneficial influence on the stability of ceramic abutments and appears to be clinically useful for premolar and molar single-tooth replacements. Available titanium inserts in the market produced by Sirona, have a single height of 4.6mm with various platform diameters for different implant systems. The aim of this in-vitro study was to determine the fracture strength of IPS-e.max CAD hybrid abutment crowns with various crowns heights by simulating cyclic masticatory loads in vitro. Materials and Methods: Forty conical AstraTech EV dental implants, 4.2 mm in diameter and 9.0 mm in length …
